A sebaceous adenoma, is a noncancerous tumor of the skin.[1] It typically occurs as a single small well-defined yellowish bump in sun-damaged skin of usually the neck and face, of a person older than age 40 years.[1] On the rare chance that there is more than one, there is a possibility of Muir–Torre syndrome.[1]

Like sebaceous carcinoma and sebaceoma, it also has sebaceous differentiaton, and is mainly made up of completely differentiated sebocytes.[1]
